Actually, taken from a post by Harpo99999 (Thanks):
"there is a change that effects entitys between entrenchment 1.02 & 1.03 the adding of a rendersheilds true after the shieldsmesh line in all entity's ships planets,planet modules and starbases.
I know as I am writing a utility to update mods for this exact reason. and some mods are not updating properly as the do not decompress properly with the convertdata_entrenchment for entrenchment mods or the convertdata_originalsins for vanilla mods"
This might perhaps be the reason, is the file you're trying to convert to TXT from 1.02? I didn't understand the quote fully but I believe that's the gist of the problem perhaps
